" RECEIVER-CASE.

.To all 'whom @'17 may concern.'

Be it known that i, HENRY C. EoERroN, a citizen of the United States,residing at Passaic, in the county of Passaic and State of New Jersey,have invented certain new and useful improvements in Receiver-Cases, ofwhich the following is a full, clear, concise, and exact description.

This invention relates to receiver cases and more particularlyto thoseprovided with a plurality of independent and separable chambers.

The object of this invention is the provision of a` receiver case,having a magnet chamber self-contained and independent of anotherself-contained structure by means of which said magnet chamber may beremovably mounted.

`in accordance with this invention, there is provided a magnet chamberconsisting of two hollow metal sections having a' gasket interposedtherebetween, i thus making a moisture-proof receptacle for the receivermagnet. Coperating with he magnet chamber is a condulet, comprising ahollow structure having a plurality of openings. One of said openings isclosed by said magnet chamber being placed thereover, and the jointformed thereby is made moisture-proof through the agency of a rubbergasket. The remainder of said openings are threaded to receive threadsformed upon the end of a conduit. Suitable attaching means is providedwith the condulet to permit its mounting in a convenient locatio In theaccompanying drawing, Figure 1 is a back elevation partly in section, ofa receiver case embodying` the features--oithis invention, and F ig. 2isla side elevation of the device shown in F ig. l. l

The receiver case shown inthe drawing comprises a magnet chamber 1formed of two hollow metallic sections 2, 3 having their edges providedwith a flange 4, 5 respectively, suitable for registering with eacnother. The flange 4 has a plurality of apertures, while the flange 5 hasa corresponding number of threaded recesses suitable to engage screws,which function to secure the sections 2, 3 together. interposed betweenthe flanges 4, 5 is a rubber gasket 6 which serves to make the magnetchamber moisture-proof. An annular boss is formed upon the front ofsection 2, which is fitted with .reducing collars adapted to accommodatean Specification of Letters Patent.

amplifying horn. Terminals 7 and 8 are provided in the base of section 3for connecting the electromagnet of the receiver 1n an energizingcircuit.

comprising the microphone no part of this invention y element forms andmay be of any The apparatus standard construction suitable for mountingwithin the magnet chamber 1.l

The magnet chamber l is attached to a conduletv 9, consisting of ahollow receptacle provided with a flange l0 adapted to t the baseportion of section 3. A rubber gasket 11 is inserted between theengaging surfaces of the flange 10 and section 3, thereby making theirunion moisture-proof. The portion of the condulet 9 adjacent a flange 10is substantially cylindrical in shape, and is provided with openings 12,l2 coinciding with its longitudinal axis. These openings are threadedfor the accommodation of the threaded end of a conduit 13. If it is notdesirable to attach a conduit to each of the openings 12, 12, a threadedplug 14 may be inserted into the vacant one. It will be apparent thatwhen the various elements carried by the condulet 9 are assembled, amoisture-proof chamber is provided for housing the terminals andconductors by means of which the receiver chamber is connected in anenergizing circuit. Depending from the body portion of' the condulet 9is a plurality of legs l5 provided with openings through which screwsmay be inserted for fastening the receiver case in any desired location.

F rom the above it will ,be seen that a receiver case embodying thefeatures of this invention is provided with two separate selfcontainedmoisture-proof chambers capable of being detached and used independentof each other or in connection with similar associated parts.

What is claimed is:

l. in a receiver case, the combination with a magnet chamber, of acondulet consisting of a hollow structure having a plurality ofopenings, one of said openings being completely closed by said magnetchamber positioned thereover, and another of Asaid openings adapted toreceive one end of a conduit.

2. In a receiver case, the combination with a magnet chamber, of acondulet consisting of a hollow structure having a plurality ofopenings, one of said openings being completely closed by said chamberpositioned thereover, means for making the joint hetweensaid magnetchamber and said opening moisture-proof, and another of said Aopeningsadapted to receive one end of a tromagnet located Within said chamber, a

leading-out terminal for connecting said electromagnet in an energizingcircuit, said terminal being secured to the base of said magnet chamber,ofa condulet consisting of a hollow structure having a plurality ofopenings, one of said openings being closed by said magnet chamberpositioned thereover, and another of said openings adapted to receiveone end of a conduit.

. 4. In acase for telephonie apparatus, the combination with anapparatus chamber of a condulet consisting of a hollow struturel havinga plurality of openings, one of said openings being completely closed bya wall of said apparatus chamber positioned thereover, la leading-outterminal secured to said wall and positioned within said hollowstructure, and another of said openings in said hollow structure adaptedto recelve one end 0f a conduit.

In Witness whereof, I hereunto subscribe my name this 5th day ofFebruary'A. D., 1916.

HENRY c. EGERTON.
